COOLING-CHANNEL FOR ORDERING TOBACCO.

SPECIFICATION forming part of Letters Patent No. 520,441, dated May 29,1894.

Application filed March 81, 1893.

To ctZZ whom it may concern.-

Be it known that I, SAMUEL P. MAYO, of Richmond, in the county ofHenrico and State of Virginia, have invented certain new and usefulImprovements in Cooling-Ohann els for Ordering Tobacco; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in cooling channels for orderingtobacco, the 0b- JGClI being to provide simple and inexpensive means foreffectually moistening air for the process of ordering tobacco.

With this end in view my invention cons sts in certain novel features ofconstructron and combinations of parts, which will be hereinafterdescribed and pointed out in the claim.

In the accompanying drawings, Figure 1 is a view in side elevation thefront of the apparatus being broken away to show the interiorconstruction, and Fig. 2 is a similar view, with the side removed.

A represents a conduit or channel preferably square in cross section,and provided with an air inlet a and outlet 1) both of which arepreferably smaller in diameter than the main or body portion of theconduit or channel. The shape of this channel is immaterial as it couldbe cylindrical or any other -shape desired.

In the enlarged or body portion of the channel are placed a series ofsheets of metal designed when in operation to be covered by a film ofwater. These sheets can be plain flat sheets as shown at c, and ifdesired can be covered on one or both sides with a cloth (1 whichabsorbs the water as it falls on the plate and by capillary attractionand gravity of the water becomes saturated from one end to the other.Instead of using plain sheets of metal as described it might bedesirable to employ sheets corrugated as shown at e. These corrugationsretard the progress of the Water downward and consequently expose it fora greater length of time to the action of the steam to be hereinafterreferred to. At

at g a single sheet of gauze, either of which Serial No. 468,464. (Nomodel.)

answers the purpose of the sheets 0 d and e heretofore described. At ItI have shown a plain sheet similar to c perforated as at 2'.

These perforations retard the flow of the thin film of water and exposethe water for a longer period to the action of the steam. These sheetswhether they be plain, corrugated, wire gauze or cloth are preferablysupported at their lower ends by rods j which latter hold them inposition equi -distant apart and prevent them from swinging. Theseplates extend across from one side to the other of the conduit orchannel and nearly the entire length and separated a suitable distanceapart to permit air to freely pass between them to receive moisture.

The pipe or channel may lie in various po sitions from nearly horizontalto vertical but preferably inclines at about an angle of fortyfivedegrees. Perforated pipes Z extend across the upper ends of the platesand discharge a constant supply of water thereto, the water beingsupplied to all the pipes Z through main 0 and the latter is furnishedwith a suitable valve 0' by which the supply is regulated.

A steam pipe S is located in the bottom of the conduit or pipe, and isprovided throughout its length with a series of discharge nozzles oropenings 8, the latter being so located relative to the sheets that ajet of steam is discharged into each space between the sheets andbetween the end sheets and the sides of the conduits. The current of airmay be blown from the bottom or drawn from the top, or it may be drawnfrom the bottom or blown from the top. In either of the latter twoinstances the steam pipe S should be at the top instead of at the bottomas shown.

The operation of the device is simple and is as follows:The current ofair forced or drawn into the conduit or channel is divided and passesbetween the plates or sheets. The air passing over and in contact withthe water with which the plates are covered, absorbs moisture and thesteam which has been discharged into the spaces between the plates orsheets and which is carried on by the current of air, becomes cool andcondensed by conpipes whereby passages are left between them,

and steam pipe entering the lower end of the channel or conduit andprovided with discharge jets at points opposite or at the lower end ofthe spaces between the sheets of material, substantially as set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

SAMUEL P. MAYO.
